Answer:

20

Step-by-step explanation:

the comment below or above me has everything right except one thing. 4 plus 2 plus 3 equals 9, Not 10. 180 divided by 9 equals 20 and there's your answer

All the interior angles of a triangle always add up to 180 degrees.

3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18

You have 3/4 of a pie leftover after your party. Each guest takes home 1/6 of the leftover pie.
Anika [276]

we know that

1) You have 3/4 of a pie leftover after your party

2) Each

guest takes home 1/6 of the leftover pie

To find the fraction of the original pie does each guest take home,

Multiply 3/4 by 1/6

so

\frac{3}{4} *\frac{1}{6} =\frac{3}{24}

<u>Simplify </u>

Divide by 3 both numerator and denominator

\frac{3}{24}=\frac{1}{8}

therefore

<u>the answer is</u>

\frac{1}{8}
